I work in manufacturing and recently inherited an assembly process that involves torqueing 4 bolts in a specific pattern, making 5 passes. I am looking for cost effective way to show the operator which bolt they should be on. I could use a PLC but it is 'not in the budget'. I can get a 24v signal every time a single torque is completed. Can anyone tell me if there is an off-the-shelf item that can get a 24v input and increment through 4 outputs? If I could just build a panel with 4 indicator lights, it would help my operators a ton. I don't know if this is the right place to ask this question. Any help is greatly appreciated.
